Abstract

In a communication system (BS) that includes an access point (B101), a repeater #1 (B102_1), and a repeater #2 (B102_2) and wirelessly communicates with a terminal (B103), the access point (B101) wirelessly communicates with the repeater #1 (B102_1) on at least a first channel included in a first frequency band and wirelessly communicates with the repeater #2 (B102_2) on at least a second channel included in a second frequency band different than the first frequency band, the repeater #1 (B102_1) wirelessly communicates with the terminal (B103) on at least a third channel included in the second frequency band, and the repeater #2 (B102_2) wirelessly communicates with the terminal (B103) on at least a fourth channel included in the first frequency band.
